A broken AC fan leaves your system running without moving air, and in a Texas summer you feel it within the hour. If the fan stops, the cooling stops. Call a technician from Thayer Air Conditioning before the heat builds up inside the house.
Key Points
- A broken AC fan traces back to one of two fans, the indoor blower or the outdoor condenser fan, and cooling stops if either one quits.
- A tripped breaker is the first thing to check, and it is the only check a homeowner should make.
- Capacitors wear out over time, and the outdoor one usually goes first because it sits in the heat.
- Failed contactors, burnt-out motors, and broken fan belts account for the rest of the failures.
- Capacitor and motor work is hazardous and belongs to a technician, not a homeowner.
Why Did My AC Fan Stop Working?
A broken AC fan means your system cannot circulate cool air, and the house heats up fast. Prompt AC repair gets the unit running again and gets you back out of the heat.
The Two Vital AC Fans
Your AC runs two fans, one in the indoor unit and one in the outdoor unit. Both are essential. If either breaks, you have no cooling.
The indoor fan is the blower fan, and it sends cooled air around the house to the room vents. It also pulls warm air through the return ducts and across the evaporator coil to cool it in the first place. Without this fan, no air comes from the vents. The blower lives in the air handler, which is why air handler repair and installation often comes up in the same conversation.
The outdoor fan lets the air conditioner release the heat it pulled out of your home. That heat has to go somewhere. The fan draws air across the condenser coil so the coil can release it, then exhausts it outside. Without this fan, the indoor unit cannot cool the air.
Why These Fans May Stop Working
Several things take an AC fan out of service. Our team has worked on every kind of AC repair here in New Braunfels, so we know where to look first. The most common causes are below.
Tripped Circuit Breaker
The first thing to check when an AC fan stops running is the electrical panel. The fan motor may have overloaded the circuit. Flip the breaker back on. If the fan trips it again, stop and call a repair technician.
Failed Capacitor
Capacitors send voltage to the motors to start them and keep them running. The capacitors for both AC fans eventually wear out, and the outdoor one usually goes first because it sits in high heat. Do not try to replace one yourself, because it is hazardous if done wrong. AC capacitor replacement is quick work for a technician with the right tools.
Failed Contactors
Contactors control the voltage flow to a motor. If a contactor breaks or gets dirty, it will not close and the motor will not run. Our technicians can replace the contactor.
Burnt-Out Motor
A motor that overheats from too much friction, often the result of skipped maintenance, burns out when its wires melt and fuse to the casing. That cannot be repaired. The motor has to be replaced. The Department of Energy covers how dirt and blocked airflow around the condenser unit drag down cooling performance.
Broken Or Loose Fan Belt
Newer AC systems use direct-drive motors instead of fan belts. An older air conditioner may have a belt break or slip loose. We do not recommend repairing that one, because a system that old is usually overdue for replacement anyway.
If the breaker is not the problem and the fan still will not turn, stop there and call. A broken AC fan is on the short list for emergency HVAC repair, because a system running without airflow can take other parts down with it.
